Hi @wohe, Can you have a look at the above issue. Thanks!

[Wyverald]

Hmm, for some reason our culprit finder pinned this on --enable_bzlmod being flipped to true (https://buildkite.com/bazel/culprit-finder/builds/7854#018bb242-8678-4450-ba11-32be8e342f96). The error message suggests nothing that would incriminate Bzlmod, though... will have to dig a bit more.

[Wyverald]

Hmm, this is probably because the bundled protobuf in @bazel_tools when Bzlmod is enabled is a higher version than what Cartographer's WORKSPACE says, and that one has an incompatible API change.

Given that this repo hasn't seen a commit in over a year, I'll just go ahead and disable Cartographer from Bazel CI.
